Design of work holding device for machining wheel hubs

- Powered Two Wheelers (PTW) are very sensitive to environmental conditions and advancement in two-wheeler safety has not kept pace with the advancement in two-wheelers. The objective of our research is to bring about an improved design for powered two wheelers, analyzing the changes through simulation and thereby improving the safety considerations. According to the databases referred regarding accidents in depth study, it is observed that two-wheelers top the chart in number of accidents by a big margin and these accidents causes more fatal injuries. To save the rider, this paper proposes to constraint the rider along with pillion to the vehicle using “Leg holding device“ and seat belt. Side airbags are employed to absorb the impact of accident. The present safety system saves the rider in frontal collisions, while this research also focuses on side collisions. ISO 13232 standard accident scenarios were followed. For simulation of scenarios multi body dynamics software called RecurDyn is used. The improvement in employing safety measures is compared with its absence and results are plotted.

Set Up

This devise addresses the inadequacies of providing a quick means of holding jobs of irregular shapes such as are encountered in small scale fabrication workshops. The conventional bench vise often does not provide the adequate grip for such shapes so that attachments in the form of V blocks are usually provided to enhance the grip before drilling operations are carried out. This versatile work holding device enables fabricators to perform drilling and other production operations on a work piece. This device produced from mild steel plates uses the toggle principle to provide rapid grip. Comparative tests on time span in the use of this device and the bench vice for job set up, production operation and then disassembly showed that time is gained with use of the device.

Spectrum Of Patients

SummaryDefinitions of mental handicap are imprecise in practice, and a wide spectrum of patients are provided for under this heading. There can be no question of specific treatment for ‘mental handicap’ as such. Many situations arising in institutions for the mentally handicapped derive from the nature of the institution and the regime. Drugs may be used ‘faute de mieux’ when environmental manipulation would be more appropriate. There is much overprescribing, and the choice of drugs is not always logical; monitoring of dose is seldom employed. A major source of behaviour disturbance in the mentally handicapped is lack of suitable occupation. Apart from a few specific indications, use of sedatives and tranquillizers for the mentally handicapped should be seen as a holding device, to enable a different system of management to be adopted or to disrupt an undesirable behaviour pattern.
